Thanks for the help!

On the personal side....
My twins are boy/girl also. Do you take them out with you? I've
been a little afraid to push it too much with them. We have done a
few 2 nighters with them w/o too much complaining. I've got them
carrying about 6 lbs (sleeping bag, foam pad, clothes, and 16 oz of
water). The hardest leg I've taken them on with their packs was
4,500 ft in 7 miles. Just curious what your experiences have been.
I'm always a little hesitant to push them too much as I don't want it
to turn into a negative experience. On the other hand, I can't wait
til they can start humping more miles and carry their fair share of
gear. I don't know if I'd know how to act carrying only my gear!
I'd have to get a different pack for sure!
